SPECIFICATION forming'part of Letters Patent No. 746,34 5, dated 1)eeemher 8,1903.

Application filed May 27,1903.

whichthe following is a specification.

This invention relates to fireproof constructions, and in the drawings is shown as adapted to the complete fireproof constructions of theaters, concert-halls, and the like.

In the drawings, in which like numbers'of reference denote like parts wherever they oc-' cur, Figure 1 is a general perspective view of my improved fireproof construction applied to theater construction. Fig. 2 is a sectional view through the balcony balustrade, floor, supports, &c. Fig. 3 is a sectional detail view of the seat-supporting steps. Fig. 4 is a partial sectional view on the line 4 4., Fig. 3. Fig. 5 is a detailed view of the construction of the ventilation-orifices. Fig. 6 is a detailed view showing the manner in which the seats are fastened to the. floor of the step-like tier con-. struction. Fig. 7 is a'sectional view through the second balcony, showing a tier of seatsupports, drawn on a reduced scale,'supportting-columns, &c. Fig.8 isa front view of the same and of the same character. Figs. 9 and 10 are viewssimilar to Figs. 7 and 8, but

- illustrate especially the construction of and supports for the first balcony.

In a theater construction it is desirable to make same asthoroughly fireproof and incombustible as is possible, and to this end I provide an improved arrangement of the ironwork serving asgeneral supports for the different floors or so-called balconies of a theater or concert-hall and also especial arrangement of supporting-framework covered with insulating material, which not only is supported by but protects theiron framework and in turn forms a strong and fireproof sup port for the rows of seats arranged in tiers or steps in a theater. It will belreadily understood that while I shall describe these arrangements as applied to the construction of the balconies, yet they might in part readily be adapted for use in other parts of the building.

The supporting-columns 1,- formed of a pair of channel-beams 2, are'suitably anchored at 3 in the concrete base. The channel-beams Serial No. 158.978 on; model-l 2 are united at-in'tervals bythe plates 3, which are securely*rivetedtheretogsoas to form of the two chanuel-b'eamsa solid column. These columns occur at suitable intervals, as seen in Figs. 1, 8,'and- 10.- Supported thereby and running fromJIcolumuto-column are the.I-'

beams 4, which in turn support the curved T-beams 5, anchoredin-the rear wall at 6, the forward ends of. said beams 5resting upon the I-beams 4. Thecolumns17,constructed like thepillars 1,:are superimposedupon said I- beams Land in turn support the I-beams 8, which in like manner receive the curved T- beams 9, anchored at 10 in the rear walls, the beams 5 formin'g supports for'athe floor and tiers of the first balcony and thebeams 9 in like manner supporting the,floor;and tiers of the second balcony or gallery,call-parts resting upon or touching each .other being suitably riveted together or otherwise fixed. The

T-beams 5 and 9 occur at intervals coincident with the recurrence of .the columns .1 and 7.

The seats 11 are arranged in rows (not shown) located upon the steps ortiers 12,:the riser part 13 of which, as. indicated in Figs.

1, 7, and 9, is higher'inthe second balcony or:

lgallery than it isinlthefirst balcony.

- The floors 14, as well as the tiers'12 and the risers 13, are covered .with'a fireproof" material, which is spread or plastered 'upon wirenetting or othersimilar reticulated material 15, which itself restsupon transverse'round iron rods orbars 16, suitably spaced apart, as indicated, for example, in Figs. 3 and4. It will' be understood that while the arrangement of the rods 16 underneath the netting 15, both beingembedded in the fireproofcomposition or insulating material 17, is indicated only in Figs. 3 and 4., yet all the iron parts and the spaces intervening between same are similarly covered with the fireproof material 17, having the netting l5and rods 16 embedded therein, and for the sake of convenience the combination of these three parts wire-plaster.

The T-beams 5 and 9, suitably spaced apart,

as hereinbefore stated,and resting upon the pillars 1 and .7, respectively, form the supports, respectively, for the tiers of seats in the first and second balconies. The construction being practically the same in both balloo conies, I shall describe that of the lower or first balcony only. In this construction the web 18 of the T-beam 5 is turned downward, while the body portion of said beam 5 supports one end of the smaller horizontal T- beam 22, which at its other end is supported by being attached in the manner hereinafter described to the small vertical T-beam 26, which at its lower end rests upon the end of the body portion of the next succeeding lower T-beam 22, which is in turn supported upon a lower portion of the body portion of the slanting large T-beam 5. smaller T-beams 22 and 26 is therefore the larger T-beam 5; but in order to insure stability of the structure the T-beams 22 and 26 are bolted, riveted, or otherwise secured together and the beams 22 to the beam 5 preferably by means of the bolts 19 and angle-plates 20. Flanges 21 are bolted to the flange or body portion 21 of the T-beam 5, as clearly indicated in Fig. 3, while the other flange of the angle-iron-20 is similarly bolted or riveted to the Web of the smaller T-beam 22. This firmly unites T-beam 22 to T-beam 5. The other end of the T-beam 22 rests upon the web of the T-beam 26 and the web 29 of the T-beam 22 and that of the beam 26 is united by the plate 28, which is bolted at 27 to the web 29 of the T-beam 22 and also to the web of the beam 26. The T-beam 26 rests at its lower end upon the next succeeding T- beam 22, being attached thereto by the angleplate 24, fastened by bolts 23 to the body portion of the next succeeding T-beam 22 and by bolts to the web of the vertical T-beam 26. The flanges 30 of the T-beams 22 have the rods 16 resting upon them and running from one of said smaller T-beams 22 to the next, which is located at a suitable distance away,and the wire-netting 15 is then laid upon these rods 16 and the plaster composition 17 spread thereon. In this way is formed upon an iron framework a solid step-like fireproof succession of supports for rows of seats. These seats may be of any desired form, but are preferably such as indicated in Fig. 2. The stem 31 supports the chair-seat 32, as well as the back 33, and is provided at its base with the flanges 34, through suitable perforations in which the bolts or pins 35 penetrate to fasten same to the floor. The seats are, however, preferably attached to the floor in the manner indicated in Fig. 6, in which the stem 31 0f the seat is shown formed with the tongue 36, below the flanges 34,which tongue 36 fits into a cup or socket 37, having the outturned flanges 38, through which the screws or pins 39 pass to unite same to the floor.

The balustrade 40 at the front of both galleries is formed in the following manner: T- beams 41 are embedded in the floor 42 of the lowest portion of said galleries and have attached to them by rivets or bolts 43 the curved T-beam 44, the major portion of which projects vertically and bears on its front the The support of the ornamental plaster-work 45 and is surmounted by the horizontal and longitudinal angleirons 46, upon which rests and to which is connected the wooden beam 47, suitably upbolstered at 48. The web 49 of the T -beam 44 has riveted to it at 50 the angle-iron 51, supporting the opera-glass holder 52, which is an additional convenience for those sitting in the front row in the balconies. The angle-iron 46 and beam 47 are attached to the T-beams 44 in this way: The angle-plate 53 is riveted at 54 to the rib 55 of the T-beam 44, and through a perforation in the horizontal portion 55 of said angle-plate 53 rivets 56 pass and also through perforationsin the horizontal portion 57 of the angle-iron 46 and into the beam 47. The T-beams 58 are riveted to the columns 1 and 7 and also at 59 to the web 49 of the T-beam 44 and is itself again secured by means of the plate 60, riveted at 61 to said T-beam 58 and at 62 to the additionally-supporting beam 63, which in turn is secured to the columns 1 and 7, spaced apart at suitable intervals. In the balustradeconstruction are the curved I-beams 64, which are riveted, by means of angle-plates 65, to the I-beams 4 and S and are additionally secured by the brace-plates 66.

Behind the seats 11 are formed in the risers 13 a series of ventilation-orifices 67, which are constructed in the following manner: Openings 68 are left in the plaster-work 69 and their opposite edges covered with channel-irons 70. To these channel-irons 70 are riveted the angle-irons 71 by the rivets or bolts 72, and the forward end of the opening 68 is faced with a frame 73, hearing the lattice 74, the frame 73 being attached at 75 and by the same bolt or rivet which fastens the angle-iron 71 to the channel-iron 70.

The angle-irons 76 run from one vertical T- beam 26 to another and form the support for the rods and wire-netting upon which the tiers 12 are plastered.

Having thus described my said invention, what I claim, and desire to secure by Letters Patent, is

1. In a fireproof construction the combination of the supporting columns and walls, beams running from column to column,beams running from the columns to the walls, horizontal beams and vertical beams both connected to said last-mentioned beams and supporting wire-plaster tiers for seats, substantially as described.

2. In a fireproof construction the combination of supporting columns and walls, beams running from column to column, beams extending from the wall to said columns, beams connected to said columns and supporting a balustrade, substantially as described.

3. In a balustrade the combination of an upright T-beam having a curve at its base, horizontal T-beam riveted thereto and conheated to the su pporting-columns ofa theaterbalcony, substantially as described.

4. In a balustrade the combination of a plurality of'horizontal beamsconnected together,

vertical T-beams curved at the lower end and attached thereto, said vertical T -beams bearing ornamental plaster-work and havingfixed at their top a bolster-bearing beam and supported by said vertical T-beams by an interposed horizontal angle-iron attached 'to said T-beams byangle-plates riveted to said T- beams and to said angle-irons, substantially as described.

5. In fireproof constructions the combination of the supporting columns and walls,

beams running from one to the other spaced apart and supporting wire-plaster ceilings, horizontal'and vertical beams of smaller dimensions attached'to said first-mentioned beams. and forming a step-like construction to support the seats, said beams of smaller dimensions supporting wire-plaster risers'and tiers, the latter-forming air-spaces between said ceilings and said risers and tiers, and veniilationopenings from said air spaces comprising an opening faced with channelthe tongues 36 of theater-seats arranged in rows, substantially as described.

In testimony whereof I have affixedmy mg 40 I nature, in presence of twowitnesses, this 20th day of May, 1903.
